citizen of the ilnited States resh nrc' luntu, in the countv ot' l uiti'm zum Georgiu have invented a :21

useful .iunirovcimgnt in.F ectiooiugnriii: Devices of whit-lithe tolloiu, Full, clear, and exact deqrriptioin reierence being had to the i'ucoinpsnying drawings,

This invent on reintes to electronu rela vsrit esp c' ll) well uduptcil lay inecl'niui riu [or operating signals on or locomotives. the signal being uctuiit". the rei'iicle engmges :1 suitable routurt her along the ch. wwn,

Such system is St described and claimrcl in my application he. 357,364, filed Fehruury 14, lt Oi'.

Une oi the objects of this invez Qon is to provide for signaling; mechanism (and purticulurly mechanism of the type indies? ml} a reliable. reluy for controiling and ope i o ing such mechanism. This relu}; is :ulupled to be operated upon the closing ot an ii(r triciil circuit in the uuiuner shove indiciitml; its opc'ution is extremely ruphh und, utter the i'noineiihu closing: of the cirrnii h :neh relzrn to operute the signrl, means are provided. for holding the ports n indirutiog position until such time as the signal may he repiuced.

I have found tl at in relay is nnuticcted by th "inn o'f the traveling vehicle, out that, upon the closing of u circuit for ii very ion of n second it will operate with. certs inty.

One of the advantages of my relay that itreduces to a minimum the time required for the initial ciosing of the relay rircr't and in e reduce the length of the c ntuct member which the traveling vehicle or the contacts carried thereby ei'igiige.

The invention comprises an arrangement of magnets and armature \vl'ierehv 151G operation above described may be realized More particularly, it incli'ides the pecni' construction of the relay and the nrrfinge ment of the circt its.

The invention may he deliuel consish ing of the combinations oi elements ombodied in the claims hereto mmexrd and do scribed in the drawings forn'iing part hereof, wherein- Figure fl represents a plan View of a. signaling device constructed in accordance with my invention, the top plate of the casing be ig. 2 represents an end inn removed; and i the some, the casing being elevution of shown in seciion.

Arm M provided near otur extremity thereof with a spring for u purpose to he described hereinafter, and the uriuuture proper 12 is provided with u lziteriii lug" 22% which is adapted to engage e lower end of on iii!!! 24 which is rigid the iii-in (it the signaling device.

denotes :1 lever pivoted to a stud 26 and having its upper end projerting upwardly in prrmimily to adjusting screw 20 and having connected thereto ii spring 27. Lever is provided with an operating arm 28 adapt ed to he brought into engagement with push pin 29 by means of spring 27 and with a, downwordly-proicctii'ur lug 28 30 and 231 denote two series of batteries. Opposite terminals of battery series 30 are connected respectively with binding posts 32 and 33. The opposite terminals of battery series 81 ure connected respectively with binding posts 35 and 34. From binding post 3; wire ifileads to one end of winding oi nnignet 8, and wire 37 lends from the other end of aid winding to binding post 38 nod 39 denote the line wires which lead 1 und C(Jilb provided with :1 common core 9 using: PlU Yllfltd with an integral operattothe external or track circuit-closer. line wires are connected respectively with binding posts 40 and 41 and said posts are in turn connected respectively with wires 1-2 and 43. From wire 35 there leads a wire 44 which is connected in parallel with indings 36 and 416 on magnets 8 and 10 respectivelyf The opposite ends of the windings 36 and 46 are connected with wire by means of Wires 47 and M respectively. Binding post 34: is connected to the same wire l-2-:as binding post 40, and 42 '5 connected to arm 14. Below arm 1 th'n-c is arranged the stop and contact screw LS, said contact screw being also connected to wire 47 \Vith the parts arranged described, the operation will be as follows: Normally current flows from battery series through winding 36, thereby energizing the magnet and retaining the armature 12 in the position shown in full lines in the drawing". Suppose that the circuit between the ends of the line wires 38 and 3f.) closed, by the vehicle traversing a portion of track suitably equippedwith a circuit-closing dcvice. This makes a short circuit through the line wires 38 and 39, and'the voltage of the combined battery series flows momentarily through the relay cmnprising windings 36 and 46. T he current flowing through winding 36 neutralizes the action of winding 36, and current flowing through winding 46 strongly energizes electro-niagnet 10, drawing the armature downwardly until spring 22 engages contact 48. As soon as contact is made between 22 and 48, another short circuit is established which takes the place of that made through wires 38 and 89 and holds the armature firmly in its new position. This circuit is made through Wires and A, windings 36 and i6, wires l7 and 47 to contact 48, through spring; 22, arm' 14: and wire 42 and binding post 3% back to battery 31.. The movement of armor ture 12 downwardly releases arm 2ifrom engagement with lug 23 and the signal disk 3 drops by gravity to the position 01 the disk 5, arm 4 engaging stud 49., this action being facilitated spring, 50. To return the armature to its normal position, the resetting rod 29 is pushed into engagement with arm 28, rocking lever 25 on. its pivot and forcing arm 2% upwardly. [is lever 25 moves upwardly, the inwardly projecting lug 28 engages am: it and moves the arms." ture upwardly, at the same time breaking the circuit through windings 36 and The circuit which includes winding 36 persists an'd the armature will be held in position by the magnet 8 energized by this circuit, and lug supports the signal. 3 in elevated position. as before. Arm 25 serves not only to reset the signling device 3, by ngaging the arm 24:, but also, by means of arin 2+2 to be elevated a suilicicnt distance to clear the supporting lug F '3 and allow latter to he swung up into cnga by the operation of lug 2 The arran entof n'iagncts, arn'iaturc and circuits ribed provides a very ctl tive and reliable relay .ud while it well. adapted for use in conncctimi with signali mechanism, I do not intend to be liinitc such use except as such limitation may be i eluded in the claim hereto annexed.
